To create Ultra Lemon Haze we crossed the Cannabis Cup winning Lemon Haze with a select Sour Diesel developed in northern California. This was then crossed with our Auto #1 to produce a stable strain that is truly unique. These genetics and the resulting strain have created something incredibly special which has made it one of our favourites.
To create Ultra Lemon Haze we crossed the Cannabis Cup winning Lemon Haze with a select Sour Diesel developed in northern California. This was then crossed with our Auto #1 to produce a stable strain that is truly unique. These genetics and the resulting strain have created something incredibly special which has made it one of our favourites. The taste is of sharp citrus, lemons and pink grapefruit, whilst maintaining the fuel like undertones of the Sour Diesel. The Super Lemon Haze was a multiple cup winner for good reason and these traits have carried through into Ultra Lemon Haze. Sativa dominant, the buds are long and dense with typical sativa shape shade leaves. The smoke is spectacular and the stone distinctly psychedelic with an excellent balance between a physical body buzz and soaring cerebral high.
Ultra Lemon Haze can be grown well both indoors and out, but indoors requires a good level of control and management to obtain the best results. Average height will be 60-70cm indoor but some phenotypes can extend up to 80cms+ if grown outdoors in optimal conditions. Due to the dominance of the Sativa genes and the lower percentage of Ruderalis this is not a standard autoflowering variety. For optimum yield and maximum psychoactivity (THC content), 90+ days are recommended. Indoors, special care must be taken. Unlike other autos the best photoperiod for Ultra Lemon Haze is 12-16 hours. It is also best to change from vegetative nutrients to flowering nutrients at week 5/6 to ensure the best crop. Outdoors, Ultra Lemon Haze can be planted from early March to the beginning of July but the flowering period will never be shorter than 60 days.
The extra time and care required for Ultra Lemon Haze will bring outstanding rewards and will leave you wanting to make this a regular addition to your grow.

Auto Seeds breeders have experimented with many types of ruderalis varieties, multiple award winning and classic strains to create a range of next generation and "super" autos. These have increased yield (in some cases comparable to photoperiod strains), excellent aroma and flavour, plus they now have drastically improved strength to match.
Whilst developing Auto Seeds we worked with many types of ruderalis, including original Siberian and Mexican genetics as well as established hybrids such as Lowryder. We only selected the best samples and crosses we made, to include in our range. For example, in our Hijack Automatic, we wanted to create an autoflowering variety with the delicious taste and soaring cerebral high of the Jack Herer (Sensi Seeds) line, but the hard hitting and long lasting power of the multi award winning AK-47 (Serious Seeds) . The result was a cross that was the perfect blend, plus it delivered an unexpectedly large yield. This typifies the extraordinary level our breeders went to in creating our exciting range of autoflowering seeds.
Based In Spain, Auto Seeds breeders work with a number of collectives and experienced breeders from Europe and North America to create, test and perfect our autoflowering range.
